RAILROAD-GATE.

SPECIFICATION forming part of Letters Patent No. 324,780, dated August 18, 1885.

(No model.)

To all whom it may concern.-

Be it known that I, J OHN JOSEPH MURRAY, Jr., residing in Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Railroad- Gates, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of one of my improved railroad-gates, parts being broken away. Fig. 2is a plan View of the same. Fig. 3 is an end elevation of the same.

The object of this invention is to provide railroad-gates constructed in such a manner that they will be closed by the approach of a a locomotive or of a train of cars, and will be opened by the departure of the said locomotive or train.

The invention consists in the construction and combination of various parts of the operating mechanism, as will be hereinafter fully described, and then pointed out in the claims.

A represents the tics, and B the rails, of a railroadtraek.

G is the gate'bar, which is pivoted at a lit-' lle distance from its lower end to a post, D. The gate-bar C is tapered toward its upper end, and its lower end is made so heavy or is so weighted as to nearly balance the upper part, so that when the gate is open and the gatebar is released the long upper part of the said gate-bar will slowly descend until the spring E, attached to its lower end, strikes against a stop-plate, F, which gradually checks the movement of the said gate-bar, and then brings it to a horizontal or nearly horizontal position and holds it there. The stop-plate F is attached to the short post G, set in the ground in proper position for the spring E to strike against the stop-plate F as the gate'bar O in its descent approaches a horizontal position.

The gate-bar 0, when open, is held in nearly an erect position by a catch-bar, H, attached to its lower part,which engages with the hook I, attached at its lower end to a shaft, J, journaled to supports K, anchored in the ground at the opposite sides of the track.

lower ends of which are pivoted to supports P, anchored in the ground at suitable distances apart. The other end of the wire N is attached to the downwardly-projecting arm Q, attached to or formed upon the short shaft 1%, journaled in bearings S, anchored in theground. The inner part of the shaft R passes beneath the rail B, and has an arm, T, formed upon or attached to its inner end, which projects upward at the inner side of the rail B, and has its upper end bent toward the head of the said rail into such a position that the flanges of the wheels of a passing locomotive or car will strike against the said arm T and force it downward, turning the shaft R and swinging the arm Q in the opposite direction.

In the ease of a train approaching the gate the arm Q will be swung from the gate and will draw thewire N in the same direction, causing it to withdraw the hook I from the catch H, and allowing the gaie-barC to swing down or close.

In the case of a train moving from the gate the movement of the shaft R will produce no effect upon the wire N.

To the shaft R is rigidly attached a downwardly-projecting arm, U, havingawcight,V, attached to its lower end, to bring the shaftR and arms Q T back to their former positions when the arm T is released from the locomoattachedto an upwardly-projecting ar1n,NV,.

attached to or formed upon the shaft X, which rocks in bearings in the lower part of the posts D, and to which is rigidly attached the lower end of a curved arm, Y, having a fricshaft will be rocked, causing the wire N to draw upon the arm W, rocking the shaft X and swinging the arm Y upward, so as to cause the friction-roller Z to press against the spring a with suificient force to raise the gate-bar 0 into an upright position, when the catch H will engage with the hook I and lock the said gate-bar C in place until released and closed by the approach of another train, as hereinbefore described.

It will be understood that this invention is exclusively designed for use in connection with doubletrack railroads.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A railroad-gate constructed substantially as herein shown and described, and consisting of the combination of the pivoted bar 0, provided with a stop-spring, E, a catch-bar, H, and an inclined lifting-spring, a, a stop-bar and post, F G, for holding the gate in place when closed, a pivoted hook, I, provided with a weighted arm, L M, for holding the gate in place when open, a shaft, X, having arms W Y and friction-rollers Z, for opening the gate, and the wires N N, connecting the catch-hook and the armed openingshaft with armed shafts operated by the wheels of a locomotive or car,whereby the gate will be worked by the said wheels, as set forth.

2. In a railroad-gate, the combination,with the pivoted gate-bar (l, of the stop-spring E and the stop plate and post F G, substantially as herein shown and described,'whereby the said gatebar' will be stopped and held in a horizontal position, as set forth.

3. In a railroad-gate, the combination,with the pivoted gate-bar G, of the catch-bar H, the catchhook I, having weighted arm L M, the wire N, and the rock shaft-R, having arms Q T and weighted arm Uv V, substantially as herein shown and described, whereby the gatebar will be held in an erect position, and will be released by the wheels of an approaching locomotive or car, as set forth.

4; In a railroad-gate, the combination,with the pivoted gate-bar O, of the inclined spring a, the rock-shaft X, having arm Wand arm Y, provided with a friction-roller, Z, the wire N, and the rock shaft R, having arms Q T and weighted arm U V, substantially as herein shown and describedpvhereby the said gate-bar will be raised into an upright posi' tion by the wheels of a retiring locomotive or car, as set forth.
